* gai_strerror() - Update string error messages according to RFC 3493.Pedro F. Giffuni2018-12-231-9/+9
| | | | | | | | | | | | | | | | | | | Error messages in gai_strerror(3) vary largely among OSs. For new software we largely replaced the obsoleted EAI_NONAME and with EAI_NODATA but we never updated the corresponding message to better match the intended use. We also have references to ai_flags and ai_family which are not very descriptive for non-developer end users. Bring new new error messages based on informational RFC 3493, which has obsoleted RFC 2553, and make them consistent among the header adn manpage.

* include: further adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-201-0/+2
| | | | | | | | | | | | | | | | | Mainly focus on files that use BSD 3-Clause license. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. Special thanks to Wind River for providing access to "The Duke of Highlander" tool: an older (2014) run over FreeBSD tree was useful as a starting point. Notes: svn path=/head/; revision=326024
* Add NI_NUMERICSCOPE.Ed Schouten2016-07-281-3/+1
| | | | | | | | | | | | | POSIX also declares NI_NUMERICSCOPE, which makes getnameinfo() return a numerical scope identifier. The interesting thing is that support for this is already present in code, but #ifdef disabled. Expose this functionality by placing a definition for it in <netdb.h>. While there, remove references to NI_WITHSCOPEID, as that got removed 11 years ago. Notes: svn path=/head/; revision=303428
* Implement an NSS backend for netgroups and add getnetgrent_r(3).Mark Johnston2016-06-091-0/+1
| | | | | | | | | | | | | | | | | | | | | This support appears to have been documented in nsswitch.conf(5) for some time. The implementation adds two NSS netgroup providers to libc. The default, compat, provides the behaviour documented in netgroup(5), so this change does not make any user-visible behaviour changes. A files provider is also implemented. innetgr(3) is implemented as an optional NSS method so that providers such as NIS which are able to implement efficient reverse lookup can do so. A fallback implementation is used otherwise. getnetgrent_r(3) is added for convenience and to provide compatibility with glibc and Solaris. With a small patch to net/nss_ldap, it's possible to specify an ldap netgroup provider, allowing one to query nisNetgroupTriple entries.

* Update the resolver in libc to BIND9's one.Hajimu UMEMOTO2006-03-211-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | Since, res_sendsigned(3) and the friends use MD5 functions, it is hard to include them without having MD5 functions in libc. So, res_sendsigned(3) is not merged into libc. Since, res_update(3) in BIND9 is not binary compatible with our res_update(3), res_update(3) is leaved as is, except some necessary modifications. The res_update(3) and the friends are not essential part of the resolver. They are not defined in resolv.h but defined in res_update.h separately in BIND9. Further, they are not called from our tree. So, I hide them from our resolv.h, but leave them only for binary backward compatibility (perhaps, no one calls them). Since, struct __res_state_ext is not exposed in BIND9, I hide it from our resolv.h. And, global variable _res_ext is removed. It breaks binary backward compatibility. But, since it is not used from outside of our libc, I think it is safe. Reviewed by: arch@ (no objection) Notes: svn path=/head/; revision=156960

| | | | | | | | | | | | | | | | | | | RFC 2553. In XNS5.2, and subsequently in POSIX-2001 and RFC 3493, it was changed to a socklen_t. And, the n_net of a struct netent used to be an unsigned long integer. In XNS5, and subsequently in POSIX-2001, it was changed to an uint32_t. To accomodate for this while preserving ABI compatibility with the old interface, we need to prepend or append 32 bits of padding, depending on the (LP64) architecture's endianness. - Correct 1st argument of getnetbyaddr() to uint32_t on 32 bit arch.

* Make the resolver(3) and many associated interfaces much more reentrant.Brian Feldman2004-02-251-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The getaddrinfo(3), getipnodebyname(3) and resolver(3) can coincide now with what should be totally reentrant, and h_errno values will now be preserved correctly, but this does not affect interfaces such as gethostbyname(3) which are still mostly non-reentrant. In all of these relevant functions, the thread-safety has been pushed down as far as it seems possible right now. This means that operations that are selected via nsdispatch(3) (i.e. files, yp, dns) are protected still under global locks that getaddrinfo(3) defines, but where possible the locking is greatly reduced. The most noticeable improvement is that multiple DNS lookups can now be run at the same time, and this shows major improvement in performance of DNS-lookup threaded programs, and solves the "Mozilla tab serialization" problem. No single-threaded applications need to be recompiled. Multi-threaded applications that reference "_res" to change resolver(3) options will need to be recompiled, and ones which reference "h_errno" will also if they desire the correct h_errno values. If the applications already understood that _res and h_errno were not thread-safe and had their own locking, they will see no performance improvement but will not actually break in any way. Please note that when NSS modules are used, or when nsdispatch(3) defaults to adding any lookups of its own to the individual libc _nsdispatch() calls, those MUST be reentrant as well.
